Description

Technical Field

[0001] The utility model relates to the technical field of aluminum-plastic bag production equipment, in particular to a bag-making device for producing high-barrier aluminum-plastic bags. Background Art

[0002] When producing aluminum-plastic packaging bags, dry laminating machines are generally used. Plastic film and aluminum foil are glued together through a dry laminating process to form a composite film, which is then processed to form an aluminum-plastic packaging bag. The aluminum foil laminating process is to apply glue between the opposite sides of the aluminum foil and the plastic film, and then the solvent in the glue is fully dried by heating and exhausting the gas, and finally the composite is carried out in a dry state.

[0003] The utility model patent with the publication number CN 220165355 U discloses an aluminum foil composite device for aluminum-plastic packaging bags. In the scheme, a frame is provided and a main film unwinding roller, a glue coating roller, a hot oven, a composite roller, a secondary film unwinding roller, a pneumatic controller, a reel and a reeling device are provided on the frame. Through the extension and retraction of two sets of cylinder extension shafts, the two sets of rotating shafts can be withdrawn from both ends of the reeling roller, so that it is convenient for the manipulator to take out the finished roll and place it on the material rack. The manipulator can also clamp a new reeling roller and place it between the two sets of rotating shafts, and the two sets are pushed toward the opposite end by the cylinder, and finally connected by the plug-in block and the strong magnetic block, so that the next reeling operation can be carried out. The cylinder extension shaft is connected and separated from the rotating shaft through the pulling structure and the hanging pin structure, which can not only drive the rotating shaft to translate, but also can be separated from the rotating shaft when the rotating shaft rotates, avoiding the noise problem and lubrication action increased by setting the rotating connection part, which is very practical.

[0004] However, there are still some shortcomings in the above scheme. Among them, it is not convenient to recycle the excess glue in the above scheme. When the two pressing rollers press the glue, the pressing rollers will press the glue to both sides, and the glue will be squeezed out from the inside of the aluminum-plastic bag and adhere to the pressing rollers. After the glue adheres to the pressing rollers, it will solidify and produce solid residues. As the glue continues to be squeezed and adhered, the residues continue to accumulate, resulting in different pressing intervals at both ends of the pressing rollers, affecting the pressing operation of the aluminum-plastic bag. In view of this, we propose a bag-making device for the production of high-barrier aluminum-plastic bags. Utility Model Content

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Embodiment 1

[0025] A bag making device for producing high barrier aluminum-plastic bags, such as Figure 1-Figure 4 As shown, it includes a frame 1; a glue recovery mechanism 2 is arranged inside the frame 1, and the glue recovery mechanism 2 includes a laminating roller 201, the laminating roller 201 is symmetrically connected inside the frame 1, and collecting chambers 202 are provided at both ends of the laminating roller 201, and a collecting hole 203 is provided on the laminating roller 201, and the collecting hole 203 and the collecting chamber 202 are communicated with each other. The glue recovery mechanism 2 can squeeze out the excess glue inside while laminating the aluminum foil layer and the plastic film with glue on the corresponding surfaces, and collect the excess glue through the collecting hole 203 and the collecting chamber 202, so as to prevent the glue from adhering to the laminating roller 201 during the laminating process, and a driving groove 204 is provided in the middle of the laminating roller 201, and the driving groove 204 is provided in the middle of the laminating roller 201. The two ends of the driving groove 204 are respectively connected with the collecting chamber 202. The cross-section of the driving groove 204 is a non-circular structure. The driving groove 204 structure can be connected with the collecting chambers 202 at both ends. The driving groove 204 is slidably connected with a piston 205. The piston 205 structure corresponds to the driving groove 204 structure. The two ends of the inner side of the driving groove 204 are fixedly connected with a limited block 206. The piston 205 structure can be slidably adjusted inside the driving groove 204. During the movement of the piston 205, the outside air can be sucked into the driving groove 204 and the collecting chamber 202, and the excess glue can be sucked into the collecting chamber 202 through the flow of air to recover the glue. The driving groove 204 is internally connected with a reciprocating rotation. The screw rod 207 and the two ends of the reciprocating screw rod 207 are respectively set through the pressing roller 201. The end of the reciprocating screw rod 207 is fixedly connected with a positioning block 208. The reciprocating screw rod 207 can drive the piston 205, so that the piston 205 can periodically reciprocate along the reciprocating screw rod 207 inside the driving groove 204, so as to realize the operation of automatically recovering the excess glue. At the same time, the driving groove 204 structure is a non-circular structure. When the reciprocating screw rod 207 drives the piston 205, the piston 205 can be limited to prevent the piston 205 from rotating with the reciprocating screw rod 207. A moving groove 209 is opened on the inner wall of the frame 1, and the positioning block 208 is slidably connected inside the moving groove 209. The length of the positioning block 208 is The lamination rollers 201 have the same diameter, and a bidirectional threaded rod 210 is rotatably connected inside the movable groove 209. The bidirectional threaded rod 210 is meshed with the positioning block 208. The movable groove 209 structure cooperates with the positioning block 208 to drive the positioning block 208 and the reciprocating screw 207, so that the positioning block 208 can be slidably adjusted inside the movable groove 209. At the same time, the movable groove 209 can limit the positioning block 208 to prevent the positioning block 208 and the reciprocating screw 207 from rotating. The bidirectional threaded rod 210 can drive the positioning block 208 to make the two positioning blocks 208 and the lamination rollers 201 approach or move away from each other, thereby conveniently adjusting the lamination spacing between the lamination rollers 201. Embodiment 2

[0026] like Figure 2-Figure 4 As shown, a collecting mechanism 3 is provided inside the frame 1, and the collecting mechanism 3 includes a sealing plate 301, which is rotatably connected to the two ends of the laminating roller 201, and a recovery pipe 302 is connected to the sealing plate 301, and a recovery pump is connected to the end of the recovery pipe 302, and a sealing pad 303 is fixedly connected to the inner side of the sealing plate 301 and the end of the inner wall of the laminating roller 201, so that the laminating roller 201 can recover the glue inside the laminating roller 201 during the laminating process, and the rotatably connected sealing plate 301 can be fixed at both ends of the reciprocating screw 207, and a feeding roller 4 is rotatably connected inside the frame 1, and a glue coating roller 5 is rotatably connected between the feeding roller 4 and the laminating roller 201, and a winding roller is connected to the end of the frame 1 away from the feeding roller 4, and a hot pressing roller is connected between the winding roller and the laminating roller 201.

[0027] When the bag-making device for producing high-barrier aluminum-plastic bags of the utility model is in use, the aluminum foil layer and the plastic film layer are moved from the feeding roller 4 to the winding roller respectively. During the movement, the glue coating roller 5 performs a glue coating operation on the corresponding surfaces of the aluminum foil layer and the plastic film layer, and at the same time, the pressing roller 201 performs a pressing operation on the aluminum foil layer and the plastic film layer coated with glue. During the pressing process, since the upper and lower parts are both pressed by the pressing roller 201, the internal glue is squeezed out to both sides. At the same time, the pressing roller 201 continues to rotate and press, and the internal reciprocating screw 207 maintains a relatively static state with the frame 1. At this time, the reciprocating screw 207 and the pressing roller 201 are in a relatively rotating state. The two pistons 205 are respectively located at the two ends of the two reciprocating screws 207. When the reciprocating screws 207 are moved along the reciprocating screws 207, the reciprocating screws 207 are in a relatively rotating state. The two pistons 205 are respectively located at the two ends of the two reciprocating screws 207. During the movement of the screw rod 207, the two pistons 205 are in a state of reverse movement, and the air at one end of the laminating roller 201 is discharged to the outside, and the outside air is sucked in at the other end. At the same time, since the two pistons 205 are in a state of reverse movement, the air intake end of one laminating roller 201 corresponds to the air exhaust end of the other laminating roller 201, thereby improving the suction effect of the glue. The glue collected in the collection chamber 202 can be collected and processed by a recovery pump, and the distance between the two positioning blocks 208 and the laminating roller 201 can be adjusted by rotating the bidirectional threaded rod 210. The hot pressing roller can heat and shape the aluminum-plastic packaging bag, and the processed aluminum-plastic packaging bag can be wound up by a winding roller.
